I got to play in a junk yard but with a 7.62Rshort in the 80`s using china copper wash steel core. well the whole bullet was steel not just the core LOL.
anyway it would pass through both doors with ease. also shot from front to back and if the engine didn't block the load it would pass all the way
I was going to blow up the car by shooting tracers in the gas tank. all it did was leak gas .
I really thought it would blow up. LOL
